Active Noise Control Communication Headsets for the Entertainment Industry

Is your current communication headset not working out for you? Do you find yourself raising the volume on your headset in order to hear the person with whom you are trying to communicate? Then, perhaps you will find this report useful. It describes active noise control and how it is currently being used in headsets to reduce the ambient noise from your surroundings, enabling you to lower the volume on your headset, reducing your noise exposure from your ambient surroundings and from the headset itself, and lowering your risk for developing noise-induced hearing loss. By the end of this report, you should understand the principle behind active noise control and how it is being employed in communication headsets. You will then be able to make an informed decision, based on your type of noise exposure, about whether an active noise control headset is right for you, and which type might be best for your work situation.

Noise and Hearing Loss in Musicians

Actsafe asked the University of British Columbia to help investigate several questions related to the noise-related health and safety of musicians and other workers potentially exposed to loud music that fall under their mandate. These questions were:

1. How much noise are musicians exposed to?
a. How do we define noise?
b. What kinds of regulations are there for the noise at music venues?
c. How loud are music venues?

2. Hearing loss in musicians: Is there a problem?
a. How well do classical musicians hear?
b. What about rock musicians?
c. What about other people who work around music, like bar and club staff?
d. What factors can increase the risk of noise-induced hearing loss in musicians?

3. What do we recommend that musicians and other entertainment professionals do to protect their hearing?
a. Changes to the environment or behaviours
b. Hearing protection devices

A comprehensive literature search was performed using several scientific literature databases, and the references of gathered articles were also searched by hand for completeness. Please refer to Appendix 1 for further details about the search methodology. Appendix 2 contains tabular information on all of the papers that were reviewed, and includes Table 1 (Epidemiology), Table 2 (Exposure Assessment), Table 3 (Disorders Other Than Noise-Induced Hearing Loss), Table 4 (Controls and Preventive Measures), and Table 5 (Papers not used for this review, but may be of interest to the reader).

Treatments for Noise-Induced Hearing Loss

This literature review was undertaken to review the status of research on available treatments for noise-induced hearing loss (NIHL) on behalf of Safety & Health in Arts Production and Entertainment (Actsafe). This review focuses on the studies that have exhibited a positive effect on NIHL in humans and that have been published since 1985.
